This is a recording I took -using a webcam- of the talk I gave at LibrePlanet 2015. The last question is missing. A better quality recording will be uploaded by the conference organizers to http://media.libreplanet.org.

Thanks again to FSF for bringing me to the conference with a scholarship, and to the donors that made that possible! Also thanks to ThinkPenguin for providing the accomodation.
